POS Troubleshooting FAQ

What is the most common POS issue?

Connection problems are usually the most common POS issues—Wi-Fi drops, Bluetooth pairing failures, and devices not recognizing card readers or printers. Many of the guides above walk through simple checks you can try before calling support.

Do POS systems work without the internet?

Some POS systems offer limited offline mode, but it depends on the provider. Toast, Square, Clover, and Lightspeed can often queue transactions when the internet drops, then sync once you're back online. Features like reporting or menu updates usually still require a live connection.

When should I replace my POS system instead of fixing it?

If you're constantly troubleshooting the same issues, dealing with frequent outages, or waiting days for support, it may be time to upgrade. A modern POS with better reliability and support can save you more in lost time and sales than it costs. If you're at that point, you can explore alternatives in our Best Small Business POS Systems guide.

Why does my POS lose Wi-Fi even when the internet works?

Most POS Wi-Fi issues aren't caused by your ISP—they're usually caused by weak signal, cheap consumer routers, overcrowded 2.4GHz channels, or devices switching between 2.4GHz and 5GHz bands. Moving your router, using a dedicated access point, or locking your POS device to a single band often fixes intermittent drops.

Why do printers and card readers disconnect during busy hours?

High-traffic times put maximum strain on routers and Bluetooth connections. Heat buildup behind the counter, interference from kitchen equipment, and POS devices being moved further away than usual all increase disconnects. Cleaning vents, relocating routers, and keeping devices within 6–8 feet can drastically reduce dropouts.

Is my POS too old to run reliably?

If your terminals or tablets can't run the latest POS app version, are stuck on an unsupported OS, or are more than 5–7 years old, you'll usually see more crashes, lag, and random disconnects. At that point, it's often smarter to look at newer systems with better hardware support and stronger connectivity instead of sinking more time into an aging setup.

Thinking About Switching POS Systems?

If you’re dealing with repeated POS issues, it may be time to look at more reliable systems built for restaurants and retail. Answer a few quick questions and see which options would work better for your business.
